Clinically node-negative oral squamous cell carcinoma poses a treatment challenge. Occult metastases occur in a significant number of patients. Surgeons traditionally perform elective neck dissection to address this risk. Sentinel lymph node biopsy offers a less invasive alternative. It identifies the first draining lymph nodes. Surgeons then examine these nodes for cancer cells. A negative […]

Mesothelioma Pathophysiology: How Asbestos Fibers Damage Cells Mesothelioma develops when asbestos fibers enter the body and disrupt normal cell function. These fibers are sharp, durable, and resistant to breakdown. Once inhaled or ingested, they lodge in the lining of the lungs, abdomen, or heart. Fiber Inhalation and Retention Asbestos fibers bypass natural defense mechanisms in […]
Researchers conduct a spatio-temporal analysis of mesothelioma incidence. They also examine asbestos exposure patterns. The study relies on statistical modeling of incidence rates. Cancer registry records and occupational history data provide the main sources. Scientists map cases across different regions and time periods. They identify clusters and changing trends. In addition, they link these patterns […]
Pathologists face challenges when distinguishing peritoneal mesothelioma from peritoneal carcinomatosis. Both conditions can appear similar under the microscope. Accurate diagnosis remains essential for proper treatment planning. Immunohistochemical and molecular biomarker analysis helps resolve this difficulty. Immunohistochemistry forms the first line of investigation. Pathologists apply a panel of antibodies to tissue samples. Mesothelial markers such as […]
KRAS-Targeted Drugs: From Molecular Discovery to Clinical Application Introduction KRAS is one of the most important oncogenic drivers in human cancer. It belongs to the RAS family of small GTPases. These proteins regulate cell growth, survival and proliferation. For decades, KRAS was considered difficult to target with drugs. Scientists struggled to find suitable binding sites […]
Analysis of Immune Checkpoint Inhibitor Efficacy in Mesothelioma Immune checkpoint inhibitors have changed treatment approaches for several cancers. Researchers now examine their effectiveness in mesothelioma. Studies stratify results by PD-L1 expression and histological subtype. This analysis helps identify which patients benefit most. PD-L1 expression serves as a key biomarker. Higher PD-L1 levels often correlate with […]
